CUTTER ATTACHMENT FOR PAPEREAPE MA()IEIIIH'ES Application filed February 3, 1925. Serial no. 6,628.

The present invention consists of a cutter attachment which is especially; adapted for application to paper tape machines to incise the tape longitudinally asit leaves ts feed roller preparatory to impinging against the moistening rollers.

One of the principal objects of this 111V611 tion is to provide a cutter capable of installation on standardpaper tape holders'and moisteners without appreciably increasing the cost of manufacture of the latter and without interfering with the normal use of the holder and moistener or otherwise impairing their etficlencyr provide a cutter which may be moved at will into an operative or inoperative position without the use of any instruments and without the necessity of removing or adjustingany part of thetape machine. 1

Other objects of the invention will be as l parent from the following description of the present, preferred form of "the invention taken in connection 3 Fig.1 is a fragmentary longitudinal sectional view of a tape holder andmoistener of standard design illustrating the application of my improved invention thereon; Fig, 2 is a top plan view of the same;

1 In the drawings, in 'order to illustrate the application of this invention apo'rtionof a rape holder and moistener, generally desig- 'nated 5', is provided, which is of standard construction and consists of a frame 6 in which a feeder supply roller 7 is revolubly rollers consisting ofa moistening roller 10' to and presser roller 11',respectively both of mounted having tape 8 wound thereon in a manner well known in the art. 'Thefree end of the tape is movable across'an inclined gu1de9 and passes betweena pair of guide which are revolubly mounted in" the frame.

I The free end of the tape is severed atany" desiredpoint and is especially adapted for use in securing the 'openends of packages, etc.

The present inventionj embo dies shaft" 12 A co-ordinate object of the invention is to with the accompanying drawings,where1n-: 1

rotatably mounted in the frame 6, in prox- I imity to the lower marginal edges of the latter.

This shaft is adapted to receive one or more cutting elements for use in longitudinally incising the tape. Tn thepresent instance, in order to illustrate theapplication of the invention, a single cutting element is shown which consists of a holder 13 the base ofwhich is provided with a transverse opening through which the shaft 12 extends.

The holder is longitudinally slit, as indicated at 14:, to provide apair of yieldable gripping jaws 15 between which a blade 16 is interposed. The holder 13 may be held in a predetermined position on the shaft 12 through the medium of a screw 17 which is detachably mounted in the base of the holder and projects into engagement with the shaft 12 as illustrated to advantage in Fig. 33.

The jaws 15 have longitudinal slots 15 formed therein which receive the shank of a bolt 18 the latterbeing carried by the blade 16. The bolt has a nut 19 threaded thereon which may be urgedinto engagement with one of the jaws 15' for contracting the jaws into snug engagement with the blade 16. By providing the slots 15 it will be apparent thatthe blade 16 is capable' of longitudinal adjustment so' as to vary the position of the blade with respect to the tape 8 in a manner hereinafter more fully set forth. 1 Moreover,

er the plate has a series of slots 22 formed therein any one of which is adapted to re- 'ceive the blade 16, or, if a plurality of cuttors are used, the blade of each cutter will be mounted in its respectlve slot 1n the restraining plate. Assho'wn in Fig. 3 the inclined guide9 of the frameis provided with slots 23 which correspondto the slo ts22 of the plate in order to permit the blade 16 to extend through the guide and into one of the slots 22. The plate 20 is disposed at an inclination complementing the angle of inclination of the guide 9 and has its lower face spaced from the upper fa ce of said guide in order to' provide ample space for the tape 8 to travel in in' being drawnfrom' the said roller 7 over the moist'ening roller 10.

One end of the shaft 12 extends appreciably beyond oneside of the frame 6 andhas a handle 2-1 fixedly mounted thereon which is spaced from the frame by a washer 25. Movement of the handle 24 correspond ingly imparts movement to the shaft 12 thereby controlling the position of the cutting blade 16. \Vhen the cutter is in an operative position, as shown in Figs. 1 and 3 of the drawings, the handle 24 is locked from movementby a clip 26 which is carried by the frame 6. Furthermore, the extent of movement of the handle 24 is limited by an abutment 27 formed by extending the lower end of the handle 14 and bending the same at right angles to'lie beneath the frame 6. In this way the handle is always readily accessible to the user of the tape holder and will not gravitate into a position below the frame 6.

In use of this device, when it is desired to incise the tape 8, the cutter is positioned substantially as shown in Figs. 1 and 3 0f the drawings, in which position the blade 16 is mounted in one of the slots 22 of the restraining plate 20. By pulling the tape through the rollers 10 and 11 in the usual manner the tape is longitudinally incised thereby providing two strips designated 8' and 8 When it is desired to use the full width of the tape the cutter is disengaged by movement of the handle 24 in an apparent manner. I

It is, of course, apparent that this device is susceptible of a variety of uses but the one herein described is designed to illustrate the principle of the invention and one of the preferred uses thereof. Moreover, various changes may be made in the device, especially in the details of construction, proportion and arrangement of parts within the scope of the claims hereto appended.

\Vhat is claimed is 1. In a paper tape machine. a frame, feed and guide rollers journalled therein and relatively spaced apart, a tape guide extending between the feed and guide rollers and inclined in the direction of the guide rollers, said guide being slotted, a shaft journaled in the frame crosswise of the guide and below the slotted portion thereof, a holder fixed on the shaft and extending inwardly of the frame, a cutter carried by the holder and penetrating the slot of the guide for longitudinally incising the tape, a plate mounted in the frameabove the slotted portion of the guide and disposed at an inclination complementing the angle of inclination of the guide with its lower face spaced above the upper face of the guide, said plate being slotted to receive the upper end of the cutter, a handle on the shaft extending in the general direction of the said holder, said handle and said holder normally tending to gravitate into a position below the frame, means for confining the gravitational movement within narrow limits, and means engageable with the said handle when the latter has reached a predetermined point between the established limits of its gravitational movement to hold the cutter in operative relation with respect to the said slotted plate.
